摘      要：Through a controllable“reactivategraftsynthetic route,two asymmetrical“Janusdendronized polymers(DPs)were successfully *** were grafted to a linear polymer motherboard by a story-by-story *** to the heterogenetic“Janusstructure,with orderly arranged chromophore moieties,the polymers demonstrated extremely large second-order nonlinear optical(NLO)coefficients and excellent NLO thermal ***-4l and DP-6l had high d33 values of 232 and 227 pm/V,respectively,which reached the highest value reported so far for linear-based polymers containing simple azo-chromophore *** controllable synthesis sheds light on the structure–property relationships of NLO polymers and other dendronized-structure functional polymers.
